Abstract

Parkinson's disease is a degenerative nervous system disorder caused by the death of dopamine-producing cells in the substantia nigra. Dopaminergic treatment could alleviate motor symptoms for a period. One of the effective dopaminergic medications for symptomatic relief was Levodopa and dopamine agonists. Clinically, Levodopa was always combined with Dopa Decarboxylase (DDC) inhibitors, which redirected Levodopa metabolism towards the COMT pathway, increasing its bioavailability in the central nervous system. The purpose of this article was to investigate the relationship between COMT and MAO-B gene polymorphisms and Levodopa in Parkinson's disease patients, starting by gathering literature on the association between COMT and MAO-B polymorphisms and Levodopa in Parkinson's disease patients using various databases. Reviewed literature revealed that the most frequent polymorphism in the COMT gene was rs4680. Some polymorphisms significantly impacted the treatment of Parkinson's disease patients. However, despite efforts to identify genetic factors influencing the risk of side effects or treatment ineffectiveness, the role of pharmacogenetics in Parkinson's disease has not been fully explored and lacks consistent clinical recommendations. Further research was needed to tailor treatment to individual polymorphisms so that pharmacogenomic approaches could be applied more consistently

Abstract

Utilizing waste into a more valuable commodity was one of the objectives of that research. Waste which initially became an environmental pollutant factor could be processed into more useful products. Tofu liquid waste was referred to whey was a by-product of tofu production. Whey was waste that still contains organic materials such as protein, fat, carbohydrates and minerals. That whey was used as a growth medium for Acetobacter xylinum bacteria and produces cellulose biopolymer as a result of carbohydrate fermentation. The process of optimizing carbohydrate fermentation by Acetobacter xylinum bacteria was carried out by varying the ratio of the amount of whey to coconut water, the acidity level of the media, and the fermentation time. The research results showed that the biosynthesis of cellulose biopolymer was obtained from a ratio of whey concentration to coconut water of 1:1, variations in acidity levels showed that the optimum fermentation conditions occurred at pH 4, and the optimal amount of cellulose biopolymer was obtained on day 21, namely with the highest percent yield value. The resulting biocellulose was characterized using FTIR, XRD, and SEM. The characterization results show that biocellulose is well formed with a fiber surface shape and particle size in the range of 50-200 nm

Abstract

The coconut plant is a plant that has many benefits for human life. Every part of the coconut plant has great benefits for life, such as the trunk, roots, fruit, even the fruit or pistil of the coconut also provides many health benefits. Villagers use coconut pistil as a traditional medicine in the treatment of diarrhea. Traditional medicine can be obtained from plants that contain secondary metabolite compounds. Secondary metabolite compounds are active compounds found in plants to defend themselves from harmful environmental attacks. The purpose of this study is to identify secondary metabolite compounds present in coconut pistils. Identification of secondary metabolite compounds is carried out qualitatively, namely conducting phytochemical tests (phytochemical screening) in the laboratory. Phytochemical Screening is a simple and effective method. The results of this study indicate that coconut pistil (pistillum Cocos Nucifera) positively contains secondary metabolite compounds of flavonoids, saponins, tannins, terpenoids and phenolics. So that coconut pistil can be used as one of the traditional medicinal ingredients

Abstract

Javan langur (Trachypithecus auratus) is one of the endemic primate species of Indonesia. Its populations were exposed to extinction risk caused by human activities. Thus, conservation efforts such as ex-situ conservation were needed to preserve this species. One of the javan langur ex-situ conservation in Yogyakarta is the Gembira Loka Zoo. In captivity, animals must be guaranteed to be free from hunger and stay nourished. One aspect to support this welfare is food supply. Therefore, this study aimed to identify the food composition and analyze the correlation between food preference and feeding duration of each food item group. We used scan animal sampling method with five minutes intervals to observe the behavior of seven individuals of captive javan langurs. The result showed that there are three groups of food (fruit, vegetable, and leaf) provided daily to javan langurs in Gembira Loka Zoo. All the individuals spent most their time to consumed food from vegetable group, except for infant female who had the highest duration in the leaf group. In addition, based on which food they consumed first every feeding time (preference food), javan langurs preferred vegetable over fruit and leaf. Based on the Spearman correlation test, there are positive correlations of duration and preference of feeding except for leaf groups. This result was different from the natural food composition of javan langurs which mostly consisted of leaves. This study might help the zoo to consider the food items provided for the animals to increase animal welfare.

Abstract

Spodoptera exigua is a major pest in onion cultivation. S.exigua larvae have a rapid spread and can cause yield losses of up to 20-100% if not controlled. Soursop leaf extract and betel leaf pesticides can cause mortality in S.exigua pests. This is due to secondary metabolites found in soursop leaf extract and betel leaf such as acetogenin, alkaloids, flavonoids, terpenoids, steroids, saponins and tannins. The purpose of this study was to determine the effectiveness of soursop leaf extract and betel leaf and the combination of both in controlling S.exigua pests. This study used a non-factorial Complete Randomized Design method with 7 treatments, namely P0 = Control, P1 = 30% soursop leaf extract, P2 = 60% soursop leaf extract, P3 = 30% betel leaf extract, P4 = 60% betel leaf extract, P5 = 15% soursop leaf extract + 15% betel leaf extract, P6 = 30% soursop leaf extract + 30% betel leaf extract. The results showed that the P2 treatment had the highest mortality rate with 67.50% mortality and the P3 treatment had the lowest mortality rate of 25.00%. Symptoms of attack show that the larvae are initially actively eating and then begin to stay away from feed, the larvae then show a change in color to brown and slowly remain still and die. The duration of pest mortality showed the fastest mortality occurred in 24 hours with the death of 20 larvae, larval mortality continued to increase with each observation. Testing on natural enemies showed results that the use of soursop leaf extract did not show any death
